for example:

Code

#![feature(allocator_api)]
use core::alloc::{AllocError, Allocator, Layout};
use core::ptr::NonNull;

struct ZST;
unsafe impl Allocator for &ZST {
    fn allocate(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError> {
        todo!()
    }
    unsafe fn deallocate(&self, ptr: NonNull<u8>, layout: Layout) {
        todo!()
    }
}
fn main() {
    let _ = Box::<i32, &ZST>::new_in(43, &ZST);
}

might be related to #94149

Probably related to #78459 (or in the same spirit) -- debuginfo code may not account for non-ZST allocator on Box<T, A>.

Actually mentioning that issue, it gives me a probable fix.

…eta, r=michaelwoerister

Only emit pointer-like metadata for `Box<T, A>` when `A` is ZST

Basically copy the change in rust-lang#94043, but for debuginfo.

r? `@michaelwoerister`

Fixes rust-lang#94725
